Inventor: PREVOTAT BERNARD
IPC: B29C48/325
Filed: 2001-03-12
Abstract: The invention concerns a continuous manufacturing method which consists in producing a blank (E) by extrusion, bringing said blank to a temperature for molecular orientation, passing said blank around a radial expansion mandrel ( 12 ); gauging and cooling while subjecting the blank to axial traction. The radial expansion produced on the mandrel ( 12 ) is partial so that the internal diameter (B) of the blank (E), when it leaves the mandrel, is less than the nominal internal diameter (D) of the finished tube; performing an additional radial expansion of the blank, up to its nominal diameter, by internal fluid pressure.

Inventor: JANACH WALTER E
IPC: E06B9/36
Filed: 2003-11-19
Abstract: A curtain system includes several flat panels made of curtain fabric or other planar materials. The top of each flat panel is provided with a horizontal metal, wood or plastic horizontal slat on which the curtain fabric or flat panel hangs in a loose manner. Both ends of the horizontal slat include a fastening device for rollers or sliders. The rollers or sliders at one end of each horizontal slat are guided inside a first common track, while the rollers or sliders located on the other end of each horizontal slat are guided inside a second common track, such that the flat panels can be slid on top of each other. The flat panels extend at an acute angle relative to the first and second common tracks and can be slid on top of each other until the flat panels nearly overlap when the first and second common tracks are mounted parallel to each other, because the fastening device therefore is designed so that the fastening device does not laterally protrude from the horizontal slat or the alignment thereof.

Patent BR-9909611-B1 (BR)
Inventor: MAURER THOMAS
IPC: G06V10/426
Filed: 1999-04-12
Abstract: The present invention is embodied in an apparatus, and related method, for sensing a person's facial movements, features and characteristics and the like to generate and animate an avatar image based on facial sensing. The avatar apparatus uses an image processing technique based on model graphs and bunch graphs that efficiently represent image features as jets. The jets are composed of wavelet transforms processed at node or landmark locations on an image corresponding to readily identifiable features. The nodes are acquired and tracked to animate an avatar image in accordance with the person's facial movements. Also, the facial sensing may use jet similarity to determine the person's facial features and characteristic thus allows tracking of a person's natural characteristics without any unnatural elements that may interfere or inhibit the person's natural characteristics.
